Hi Anton
Sorry for the delay in getting back to you on this. How old is the
version of Thinking Sphinx that you're using? I've not been using
WillPaginate's Collection class for some time (Thinking Sphinx has
it's own now), and that'd be why the method doesn't exist.
Mind you, if you're using a version of TS that's been around for the
last 6 months or so, then I'm going to be confused :)
